nndeploy::base::Range Class Reference

Template class specifying a continuous subsequence (slice) of a sequence. The class is used to specify a row or a column span in a matrix ( Mat ) and for many other purposes. Range(a,b) is basically the same as a:b in Matlab or a..b in Python. As in Python, start_ is an inclusive left boundary of the range and end_ is an exclusive right boundary of the range. Such a half-opened interval is usually denoted as . The static method Range::all() returns a special variable that means "the whole sequence" or "the whole range", just like " : " in Matlab or " ... " in Python. All the methods and functions in OpenCV that take Range support this special Range::all() value. But, of course, in case of your own custom processing, you will probably have to check and handle it explicitly: More...

Detailed Description

Template class specifying a continuous subsequence (slice) of a sequence. The class is used to specify a row or a column span in a matrix ( Mat ) and for many other purposes. Range(a,b) is basically the same as a:b in Matlab or a..b in Python. As in Python, start_ is an inclusive left boundary of the range and end_ is an exclusive right boundary of the range.

But, of course, in case of your own custom processing, you will probably have to check and handle it explicitly:

void my_function(..., const Range& r, ....)
{
    if(r == Range::all()) {
        // process all the data
    }
    else {
        // process [r.start_, r.end_)
    }
